River Eden, Carlisle - Underwater Concrete

To repair the deteriorating riverbed was a specialist one which made both local and national news.

Situated in Carlisle, Cumbria, the River Eden railway viaduct recently required an urgent repair solution to the deteriorating riverbed condition, where trains were having to operate at reduced speeds of 20mph over the Victorian and 1940s-built structures.

Detailed laser surveys carried out by Network Rail showed fast flowing water on the River Eden had caused parts of the riverbed to wash away, posing a risk to the viaduct foundations.
